Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 0.43/day in the week to Sep 11 → 0.71/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

I may have not played a lot but it was really fun.
Similar to other bullet hell games. It's entertaining for a couple hours

爽玩
好玩,爱玩。 完成了难度1以后,用无尽模式练手,就可以慢慢总结出经验了,比如如何叠Buff,如何把看似没用的器官搭配起来使你的输出更强大,不在无尽模式下练习几个小时是比较难掌握这些心得经验的,经量不要急着冲击后面的关卡,先把这些搭配练的比较熟了再玩后面的关卡会比较容易。
muy facil recomendado para pasa el tiempo en 1 horas lo completas jajaj es divertido y facil de entender solo falta mejorar la traduccion a español
